Rapidly urbanising areas in Asia cause a growing concern about contamination of waters, soils and crops due to inappropriate use of urban wastes and agrochemicals and (wet and dry) atmospheric deposition. The problem remains poorly quantified so flawed will contribute to participatory farming strategies that focus on effective water and nutrient recycling and stakeholders' interaction, to sustain integration between rural and urban areas. We, a multidisciplinary research consortium involving farmers and extensions, will do this via an Integrated Knowledge Based System approach, where Modelling, Database development, Participatory methods will be combined. The project will deliver results and methods for strategic applied research and secure interactions with policy makers and extension. Two sites in lowland urban-urban areas of China and Vietnam will provide contrasts and similarities as a basis for extrapolation.
